4 Claims.

This invention relates'to clothes wringers and particularly to powerdriven wringers such as are used in domestic washing machines. Thegeneral structure, including the lock and release 5 mechanism of thiswringer is similar :tothat of Y the rolls;

Another object is to provide pressure mechanism actuated by four helicalcompression springs adjustableto exert proper wringing pressure underall conditions; and

A still further object is to provide pressure mechanism which permitsthe top of the top frame to be smooth and unencumbered by the pressuremechanism. 7

Fig. 1 is a sectional elevation view disclosing the parts of my pressurere-set mechanism and their relation tothe major elements of the wringer.f

Fig. 2 is a sectional end elevation on the section lines 22, Fig. 1showing the wringer rolls in pressure relationship;

Fig. 3 is a sectional elevation view on the section lines 2-2, Fig. 1,the same as Fig. 2, but showing the compression springs and rolls asthey would appear just before the lower roll is released into tensionrelationship with the locked upper roll as illustrated in Fig. 5 andwhich later will be explained in detail.

Fig. 4 is a broken sectional front elevation view showing the pressurere-set mechanism about to start the actuating downward stroke of thehinged top frame;

Fig. 5 is'a broken. sectional front elevation mechanism after thedownward stroke of the top frame has been completed with the rolls inlocked pressure relationship as illustrated in Fig. 2.

Now referring to Fig. l, the numeral 20 designates the lower frame whichhas been broken off on its inner end to eliminate the gear head which isnot included in this invention. The numeral quickly and easily efiectproper pressure between 2! designates the top frame which is hinged tothe lower frame by the pivot rod 22.

Thelower roll 23 and the top roll 24 are journalled in bearings 25 and26respectively. It will be noted that the journal shaft of the upper roll24 is linked to the top frame by transverse members I9 so that it mayhave slight upward and downward-movement with respect to the top framebut will beretained thereby and has a cross bar 21 to provide drivingconnection with the wringer gear head not shown.

' It is also to be'understood that my wringer employs a top roll drivewhich is disengaged from the driving means when the top frame 2| ispivoted upwards.

Outwardly extending from the pivot 22 of the top frame 2| is abifurcated cam lever 28 which bears against a bail link 29 which is heldin central relationship with the cam lever 28 by the lock bolt 30 whichpasses slidably through a hole in 29 and between the bifurcatedprojections of the cam lever 28. 7

Near the lower end of the bail link 29 is the notch-29' designed toengage the lip 32' of the bell crank 32.

The baillink 29 isattached by welding to an- .other horizontallyextending bail link 3! whose sides pass around thebell crank 32 andwhose crossed end section is slidably supported on the rod link 34 whichis pivotally supported in holes 34' of the bell cranks 32. It will benoted that the two bell cranks 32 are pivotally supportedby pins 33 andsupport'at the outer end of the crank link members 35 on pins35'. p

These linkmembers 35 extending substantially vertically are pivotallyattached to the lower bearingsupport 31 by cross pins 38 throughelongatedslots 36.. Also supported on the pin 33 on the outward end ofthe wringer is the lever member 39which bears against a vertical plungerrod 40 on its upper end.

The lower end of the levermember 39 is bifurcated and bears against thetube 4| on the rod link 34. This tube member bears against the closedend of the bail member 3| which is tensioned outwardly by thecompression spring 42 and the cotter pin 43.

Rivete'd to the frame 20 on the outward end is a lock member 44 and anangular deflecting member 45, positioned to engage the pivotal latch 41which is tensioned outwardly by a torsion spring 48 around the pivot 46.A rocking lock member 49 extending longitudinally in thetop frame isrockably supported at the points 5|].

Pinned to this rockable member 49 are release bars 52 extending alongeach side of the top frame 2| and connecting to the member 49 by pinsthrough holes 5| in the side of the top frame 2|.

Normally the rocking member 49 holds the lip 47 of the latch G1 inlocked relationship but by pivotal movement, the lip 41 is allowed toescape through holes 49 thus releasing the latch 41 from the lock 44.

It will, therefore, be understood that by pressing inward on the releasebar 52, the top frame may be thus unlatched.

Having thus described the parts in their relation to each other, I willnow describe the operation of the wringer.

Operation Assuming the wringer to be in locked pressure relationship andin operation, by pushing or pulling the release bar 52, the lip 41' ofthe latch 41 is allowed to escape through the slots 49' and the top baris thus unlatched at M permitting the top frame to pivot about the rod22, thus releasing the pressure between the rolls.

By lifting the top frame as in Fig. 4, the bail link 29 drops down andthe notch 29 engages the lip 3'2 of the bell crank 32, the link 29 beingimposed inwardly to accomplish the above engagement by the spring 42.

Further downward movement of the top frame as shown in Fig. 5 results indepressing the lower roll in its bearings against the compressionsprings 53 as shown in Fig. 3. This is accomplished by a lever systemactuated by the top frame 2| on the rod 22 as a fulcrum through the camlever 28, the vertical bail link 29, the horizontal bail link 3| whichresults in forcing the bell cranks 32 around their pivots 33 whereby thelinks 35 pull down the lowerbearing supports 31 whose horizontal ears3'! compress the springs 53 as shown in Fig. 3.

At this point, as shown in Fig. 5, the plunger rod All now contacts theupper frame 2| and continued downward movement pivots the lever 39 aboutthe pivot 33 against the tube 4| whereby the horizontal bail link 3'l ismoved outward to disengage the notch 29 of the link 29 from the lip 32'of the bell crank 32.

While this is occurring the latch 41 has been forced under the lip ofthe lock 44 by the angularly disposed member 45 and when'the lip 32 ofthe bell crank 32 is finally released from the notch 29, the lower roll23 is tensioned upwardly by the springs 53 guided by the adjustablestuds 54 against the upper roll 24 held in the upper frame 2| in lockedrelation to the lower frame 20.

The wringer is now again in operating position and the complete cycle ofoperation will be well understood.

Having thus described my device, I now claim as new:

1. In a wringer roll pressure reset mechanism, a lower frame, a lowerroll, springs resiliently supporting said lower roll in said lowerframe, an upper frame pivoted at one end upon a pivot extendingtransversely of the lower frame for swinging movements, an upper rollmounted in said upper frame and cooperative with said lower roll incertain positions, a releasable latch for securing said upper frame tosaid lower frame, dual link bell cranks associated with a releasablelink actuated by downward pivotal movement of the top frame fordepressing said lower roll against said springs until the frames arelatched together with the rolls separated, and re lease means for saidlever system operative upon the movement of said top frame to apredetermined latching position for releasing the pressure of saidsprings to said rolls to put said rolls in pressure relationship.
